Pleural thickening may be organized into two categories: diffuse and focal. Diffuse pleural thickening (DPT): Thickening of 50% or more of either the left or right pleura. DPT may also be diagnosed in a patient with thickening of 25% or more of both pleurae. Focal pleural thickening: Thickening confined to one or more specific areas of the pleura.
